American tech giant Apple is testing a feature that will let users Face ID to unlock the phone even when wearing a mask.

According to Business Insiders, the iOS 15.4 beta added a new feature designed to allow Face ID to be used with a mask and without an Apple Watch for authentication.

The tech giant said that the feature can “recognize the unique features around the eye” for authentication purposes.

If users opt to use this feature during setup, they will need to rescan their face for Face ID. From there, Face ID will be able to unlock your iPhone even when they’re wearing a mask.

In the Settings app, there’s a new ‘Use Face ID with a Mask’ toggle that can be turned on or off if you change your mind about the mask, and there’s a new feature to ‘Add Glasses’ to make Face ID more accurate when they’re wearing glasses and a mask at the same time.

Apple warns in the Settings app that Face ID is “most accurate” when it’s set up for full-face recognition only.
